FASTENER FOB, CONCRETE STRUCTURES FOR BASES OR OTHER PIECES.

Specification of Letters Patent.

Patented Mar. 12, 31918.

Application filed May 24, 1917. Serial No. 170,619.

To all whom it may concern:

Be it known that 1, JOHN GOULD, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Fastener for Concrete Structures for Bases or other Pieces, of which the following is a specification.

My invention relates to a structure or building made of concrete or other similar material, and consists of a fastener in the structure adapted to hold firmly a wooden wall, a ground piece, a floor or corner piece, a chair rail, a base board, a picture rail, or other members of any kind under various names employed in finishing or trimming an apartment or room, as will be hereinafter set forth.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figures 1, 2, 3, and 4: represent different forms of fasteners for the purpose described, embodying my invention, in Fig. 3 one of the facing blocks employed having been removed therefrom.

Fig. 5 represents a longitudinal section on line 5-5 Fig. 1. v

Fig. 6 represents a transverse section on line 66 Fig. 3.

Fig. 7 represents a transverse section on line 77 Fig. 4.

Similar numerals of reference indicate corresponding parts in the figures. Referring to the drawings 1 designates a plate preferably of metal, the same having thereon a pair of tongues 2, and lips 3, it being noticed that said lips and tongues are punched out of said plate and properly bent up therefrom, said lips being inturned toward each other from the inner terminals of said tongues forming angles therewith.

4 designates a block of wood which has in its sides the grooves 5, it being noticed that the body of said block is placed over the central portion of the plate 1 and rested on the contiguous margins of the latter, its sides being embraced by thetongues 2, and

its grooves receiving the lips 3 by which means the block is firmly anchored on and connected with said plate, its hold thereon being increased by inclining said tongue inwardly and inclining the contiguous portions of the block whereby the latter is united with the tongue by dovetailed joints.

It will be seen that the plate with its block may be applied in position on a wall, partition, backing, etc, or other place of service, the plate being cemented in place and embedded in the concrete, or similar material of a structure or building while the block is exposed so that a facing strip 6 may be nailed conveniently and efiiectively, or otherwise fastened thereto, as shown in Fig. 5. Such strip may be a wall piece, a floor piece, a wash board, a base board, a door or window frame trimming, or other piece or finishing or trimming board member of any kind in an apartment, room, etc, of the structure or building, the block being firmly retained in place on the plate without being liable to be removed therefrom by outward draft, warping, etc., and so the piece, board, trimming or other member of the kind, etc., will remain connected with the block.-

Again there is a plurality of pairs of tongues in the opposite ends of the plate, and thus the block will be held simultaneously near each end, thus doubly connecting the block and the'plate with each other.

The plate will have openings 7 therein to allow the concrete or cement to flow therethrough as a clench for the plate, and so additionally holding the latter in position. The fastener may be a fiat piece with a single block thereon, as in Figs. 1 and 2, or angular, as in Figs. 3, 4, 6, and 7, in which latter instances the plate is equipped with my means for holding a block therein on each limb thereof.

Owing to the grooves in the block, the side tongues and the end lips are slidable into position when they are immediately .held connected with the plate by means of double action of the lips and tongues on the block, said tongues and lips being of superior strength owing to their integral connection'with the plate from which they are turned-out.

Should the blocks require renewal, they may be removed from the plates by sliding them out of the same without the lips and tongues on the plates or the plates themselves preventing the same.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. A plate of the character stated having a pair of integral tongues on the sides thereof, each tongue provided at its inner terminal with a lip, said lips being inturned toward each other from the inner terminals of the tongues forming angles therewith, combined with a facing block of wood slidable on said plate between the said tongues and having edge grooves for the reception of the lips.

2. A plate of the character stated for a fastener for concrete structures having inte gral' tongues on the sides thereof in pairs, each tongue provided at its inner terminal with a lip, said lips being inturned toward each other from the inner terminals of the tongues forming angles therewith, combined with a facing block of wood slidable on said plate between the said tongues and having edge grooves for the reception of the lips, the opposite faces of said block being beveled and the tongues correspondingly inclined to closely contact with said beveled sides.

3. A metallic plate for a fastener for concrete structures, the same being of angled form, each limb thereof being provided with integral tongues in pairs, each tongue having a lip and the lips of opposite tongues being inturned toward each other from the inner terminals of the tongues forming an gles therewith, the saidpairs of tongues being spaced from each other.

4:. A metallic plate for a fastener for concrete structures, the same being of angled form, each limb thereof being provided with integral tongues in pairs, each tongue having a lip' and the lips of opposite tongues being inturned toward each other fromthe inner terminals of the tongues forming angles therewith, the said pairs of tongues being spaced from each other, combined with facing blocks of wood inserted between said tongues, said blocks resting on the margins of the plate and clamped by said tongues and formed in their opposlte sides With grooves to slidingly receive said lips.

JOHN GOULD.
